True 3-D display technology developed by European researchers offers enormous potential for design, education and collaboration. Star Trek's holodeck is a famous science fiction concept. The holodeck is still science fiction, but last year researchers took the first, confident steps towards its realisation with the Coherent project. This EU-funded research project, developed a commercial, true 3-D display that could one day be called Holodeck version 1.0. It is called HoloVizio. The researchers based the display component on innovative holographic techniques that can present, at natural human interaction scale, realistic animated 3-D images simultaneously to an unlimited number of freely moving viewers.
